1 Claim. (Cl. 240-73) This invention relates to a lighting fixture in which the light socket is adjustable for casting a spot light in various angular directions.

The invention has particular reference to a lighting fixture in which the light socket is swivelly mounted for movement through an angle of 90 degrees in all directions throughout -a complete circular plane. The arrangement is such that the light socket can be adjusted and set in various adjusted positions to cast a spot light upon an part of a forward circular plane.

While lighting fixtures have been adjustable to cast a light in different angular directions, the same have not been capable of universal swinging for spot lighting any portion of a forward plane. In order to overcome the limited adjustability in prior constructions, the present invention comprehends the pivotal mounting of the light socket for turning movement on axes located in right angular relation and for the movement of the hood or reflector with the light socket.

Another object of the invention is to provide a mounting for one or more spot lights which are independently adjustable and arranged with two or more of the mountings adapted to be disposed in end to end interfitting relation.

Still another object of the invention is to provide a lighting fixture of said character in which the spot lights are readily adjustable to any desired position by fingertip movement thereof.

'Still another object of the invention is to provide a hood or reflector which is connected with the socket to permit of circulation of air through the base of the hood or reflector.

A further object of the invention is to swivelly mount the light socket on the cover of the lighting fixture which is removably connected with the fixture.

With the foregoing and other objects in view, reference is now being made to the following specification and accompanying drawings in which the preferrred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a perspective View illustrating a lighting fixture having three swivelly mounted light sockets constructed in accordance with the invention.

Fig. 2 is an enlarged fragmentary plan view showing one of the light sockets with the hood and light bulb removed.

Fig. 3 is an enlarged fragmentary vertical sectional view taken approximately on line 33 of Fig. 2.

Fig. 4 is a cross-sectional view taken approximately on line 44 of Fig. 3 With the hood and light bulb partly broken away.

7 n Referring to the form of the invention illustrated in Figs. 1 to 4 inclusive of the drawings, the lighting fixture v of the drawings.

which is mounted one or more electric light sockets 11, three being shown in the embodiment illustrated in Fig. 1

The box 10 is of rectangular formation and includes a rear wall 12, opposite side walls 13 and .14, opposite end walls 15 and 16, and a flanged cover 17 which is secured in closed relation with the box by screws 18 afiixed to the rear wall' 12 and protruding through openings in the cover and engaged by nuts 19.

The end wall 15 is recessed inwardly from the end of the box, While the end wall 16. projects outwarly of the ends of the bottom wall and opposite side walls and the central portion of the socket protruding through the. central opening 24 in said plate. The plate 22 is provided 7 with rearwardly projecting cars 25 which are located on a diametric axis and are pivoted to a ring member 26-on pins 27. The forward edge of the ring 26 and the forward face of the plate 22 are located substantially flush with s the forward face of the cover 17 when the socket 11 is in right angular relation with the cover. The pins 27 extend through spring washers 28 located between the ears 25 and the ring 26' and which prevent too free turning of the socket on the axis defined by the pins 27.

The ring 26 is pivoted on pins 30 to the inwardly directed ears 31 of angle members 32 atfixed to the inside face of the cover 17. The ears 31 are located on a diametric axis and at right angles to the ears 25. The pins 30 protrude through spring washers 33 locatedv between the ring 26 and the ears 31 to prevent too free movement of the ring on a horizontal axis extending through the pins 30. The socket 11 together with the plate 22 may be swung through an arc of approximately ninety degrees on the axis through the pins 27 and the ring 26 together with the plate 22 and the socket 11 may be swung through an angle of approximately ninety degrees on the axis extending through the pins 30 so as to dispose the light socket in any desired angular position.

A hood or reflector 34 is provided for each socket which extends outwardly beyond the forward end of an electric light bulb 35 in each socket with the outer end of the hood or reflector 34 being substantially of cylindrical formation for directing the light rays emanating from the light bulb in the form of a spot light. The hood or reflector 34 is secured to each of the plates 22 by spaced screws 36 which extend through spacer elements 37 so as to space the inner end of the hood or reflector from the plate 22 to permit of air circulating about the inner end of the hood, and for this purpose, the hood or reflector is formed with an opening 38 which issomewhat larger than the inner end of the light bulb 35 to permit of the passage of air through the hood or reflector for ventilating the same.

The end walls 15 and 16 are provided with knockout portions 40 through which protrude the light conds 41 of the socket for connecting the same with a source of current. When the lighting fixture is provided with a plurality of light sockets, the light cords 41 may be connected together within the box 10 to connect the same in series and when two or more of the lighting fixtures are disposed in end to end relation the light cords 41 may extend into the adjacent fixtures for connecting all the lights together.

In the form of the invention illustrated in Fig. 5 of the drawings, the lighting fixture includes a base 43 which is Patented Apr. .30, 1957 in the form of anelongated box of triangular formation in-cross-sectiom Theboxisrclosedtby a cover 44 on which are swivelly mounted one or more electric light sockets 45 similar to the mounting of the sockets ,11 in the previous form of the invention; In this'form the light socket is secured toa forward plate 46 havingiin- Wardly directed ears-47"which are pivoted to-aring48'on diametric pins" 49, and in right angular relation "therewith the ring 48 is pivoted to inwardly directed ears 50" flange 58 of the wall 54. The cover 44 is similarly pro:
